jsTree和上下文菜单：修改项目

Question

我正在使用jsTree 3.0.0，我需要通过以下方式之一修改上下文：

• 更改默认项目的标签语言，禁用某些默认项目并添加新项目。
• 重写所有项目并将一些新项目绑定到创建，重命名和删除功能。

我尝试了几种方法，但没有任何效果。例如，当我点击“创建”时，这会返回Uncaught TypeError: Object [object global] has no method 'create'。

"contextmenu":{
    "items": function($node) {
        return {
            createItem : {
                 "label" : "Create New Branch",
                 "action" : function(obj) { this.create(obj); alert(obj.text())},
                 "_class" : "class"
            },
            renameItem : {
                 "label" : "Rename Branch",
                 "action" : function(obj) { this.rename(obj);}
            },
            deleteItem : {
                 "label" : "Remove Branch",
                 "action" : function(obj) { this.remove(obj); }
            }
        };
    }
},

如果我尝试添加一个项目，如下一个示例所示，我将松开默认菜单项：

items : { 
    "create_folder" : {
        "separator_before" : false,
        "separator_after" : false,
        "label" : "Create Folder",
        "action" : function (obj) { alert(1); /* this is the tree, obj is the node */ }
    }
}

我哪里错了？

解决：

"contextmenu":{         
    "items": function($node) {
        var tree = $("#tree").jstree(true);
        return {
            "Create": {
                "separator_before": false,
                "separator_after": false,
                "label": "Create",
                "action": function (obj) { 
                    $node = tree.create_node($node);
                    tree.edit($node);
                }
            },
            "Rename": {
                "separator_before": false,
                "separator_after": false,
                "label": "Rename",
                "action": function (obj) { 
                    tree.edit($node);
                }
            },                         
            "Remove": {
                "separator_before": false,
                "separator_after": false,
                "label": "Remove",
                "action": function (obj) { 
                    tree.delete_node($node);
                }
            }
        };
    }
}

                    $node = tree.jstree('create_node', $node);
                    tree.jstree('edit', $node);
                }
            },

                }
            }
        };
    }

对于jstree v3。+（i test 3.2.1）这个例子工作

"contextmenu":{
                    "items": function () {
                        return {

更具可读性的例子

 var tree = $('#treeDiv').jstree({
        "plugins": ["contextmenu"],
        "contextmenu": {
            "items": function ($node) {
